File:Boldness and links tutorial.ogv Wikilinks are one of the key components of Wikipedia. Wikilinks connect pages to each other, tying the whole encyclopedia together.
In general, wikilinks should be added for the first mention of important or unfamiliar concepts in an article.
Typically, wikilinks use square brackets, like this: [[target page]]. You can also insert them by clicking the 
icon.
If you want to link to an article, but display some other text for the link, you can use a pipe | divider (Template:Key press):
[[target page|display text]]
You can also link to a specific section of a page using a hash #:
[[Target page#Target section|display text]]
Here are some examples:
[[link]]displays as link[[Android (operating system)]]displays as Android (operating system), whereas:[[Android (operating system)|Android]]displays as Android[[Earth#Chemical composition|Chemistry of the Earth]]displays as Chemistry of the Earth
You may also encounter templates, which allow frequently used elements to be included on multiple pages. These are designated by curly brackets like: {{template name|parameters}}
For instance, to insert the [citation needed] tag, you can type this code:
{{Citation needed|date=December 2024}}. The 
icon works, too.
